I'm constantly getting asked what type of sous vide circulator someone should buy. This used to be an easy question to answer because there were only one or two reliable machines but now there are several options, all of which are generally comparable and can get the job done.
I decided to put together this article to help people quickly get an overview of the top circulators. I've focused on the major deciding factors I think are important such as heating power, how loud it is, and the price.
To help with this, I reference a few of our sous vide benchmark tests such as Heating Power (how fast the circulator can heat the water), Sound Level (how much noise does the machine make), and Power Consumption (how much power does the machine use).
